A pristine copy of Action Comics No. 1, the first appearance of Superman in 1938, sold for a record $3,207,852 Sunday in an auction on eBay. Darren Adams, the owner of Pristine Comics in Federal Way, Wash., began the auction on Aug. 14.

The auction had a 99-cent starting bid and had reached $1.6 million within two hours.

The issue by Jerry Siegel and Joe Shuster is now the world's most expensive comic, surpassing an Action Comics No. 1 owned by actor Nicolas Cage that was sold for $2.16 million in 2011 on the auction website ComicConnect.com.

Both comics were graded as a 9.0 (out of 10) by the independent third-party grading service Certified Guaranty Company (CGC), but Adams' copy was labeled as having "perfect white pages." With a print run of approximately 200,000 in 1938, less than 100 are thought to be in existence, and CGC has only graded seven unrestored copies of Action Comics No. 1 over a 6.0.

The lucky winner is also giving back — 1% of the proceeds from the same will benefit the Christopher & Dana Reeve Foundation, an organization dedicated to helping individuals with spinal-cord injuries and paralysis that was started by the Superman movie star.
